String Theory, Quantum Gravity and Black Holes (Or, Are We Holograms?)

Hey I’m a 20 year old kid who never had the money for school but I teach my self about these theory’s and I love to watch you alot Mr. Briangreen

It’s great when both the interviewers and interviewees know their shit extremely well

Just gotta say this: something I really like about Brian Greene is that even though he has opinions on the topic his interview subject is discussing and could easily BE the one being interviewed at any moment, he carefully doesn't interrupted his guests and lets them say what they have to say in their own way. As obvious as it is that doing so is literally the POINT of interviewing guests, almost NO ONE who does it seems to be able to get out of the way. The great Terry Gross of course is the absolute master of interviewing and Brian Greene is just like her in this respect. Thanks Brian.

Juan Maldacena lives somewhere on the boundary of the Universe. My head is spinning.

I'll watch it again-I feel compelled to try to understand some of this stuff but it makes my head hurt like nothing else I've ever encountered! Brian Greene is a RockStar!

I think it is fair to say that the smaller we go, the more complex the Universe is, and this phenomenon is relative across the board. I would suggest that the puzzle is infinitely long. If String Theory is the only mathematically possible explanation, these idea's should be pushed to exhaustion, or until someone develops a radicaly better theory. As it stands the scientific explanations are incomplete, and unsatisfactory, which leaves more space in the human mind to seek for alternatives.There is a balance and a breaking point but we're not there yet, therefore this cannot be deemed as unproductive time spent. Keep up the good work!

Hello everyone, i dont want to show off but , I'm 11 and very interested in learning theories describing our universe so thankyou for this discussion .

I liked Brian,s comment that juan Maldacena was diplomatic about loop quantum gravity

I remember when I was student and a class day The Quantum Mechanics was introduced, I thought while professor was developing ideas and equations, "this is a lie .. this is forced , forcing a particle being a wave. It's a patch for information we haven't about microscopic world. If my girlfriend says to me "tonight I will go out with old friends for a pizza, I will return to 23:00 o'clock. So, I can calculate probabilities if she got to eat pizza, or go to bar to drink beer, or go to a party, now she behaves like a wave 😂
